Popis: Aim. To assess the adaptive potential of cardiovascular system in female population of the Russian Arctic territory and its relationship with sex hormones and dopamine levels.Material and methods. The study involved 253 women living in European North (Arkhangelsk Oblast) and Asian North (Yamalo-Nenets Autonomous Okrug), who were divided into groups of fertile (n=58 and n=70, respectively) and postmenopausal women (n=59 and n=66, respectively). Enzyme immunoassay of serum was used to determine the levels of follicle-stimulating and luteinizing hormones (LH), progesterone, prolactin, total and free testosterone, estradiol, sex hormone-binding globulin. In plasma, dopamine level was identified. Adaptive potential (AP) was estimated according to R. M. Baevsky method.Results. A significant disadaptation was revealed in residents of Asian North compared to European North as follows: the proportion of persons with poor adaptation increases from 16% in European North to 26% in Asian North in fertile women, while the proportion of persons with adaptation failure increases from 9 to 23% in postmenopausal women. The strongest relationships between hormonal parameters and AP level were found in postmenopausal women: in European North, adaptation impairment is associated with higher levels of testosterone at lower concentrations of follicle-stimulating hormone, LH and sex hormone-binding globulin; in Asian North, adaptation failure is associated with lower values of LH, prolactin, testosterone, and dopamine.Conclusion. A greater AP impairment, which characterizes cardiovascular system adaptation, was noted among Asian North residents. We revealed significant relationships between cardiovascular function and hormonal parameters. In European North residents, poor adaptation is associated with a more androgenic sex hormone profile, while in Asian North — with lower values of LH, prolactin, testosterone and dopamine.
